Much better actually and my repeatability at track improved. It greatly reduced my deviations. Keep in mind we have dramatic temp swings up here which is really what drove me to do the conversion. Motor is a stroked 440 making just north of 630HP on pump gas. Car just a bit under 3k pounds weight distribution excellent. To say the car was temperamental due to outside temps is an understatement. Tuning was sheer chaos. Keep in mind I am not the best carb tuning guy either. The EFI solved both my ineptitude as a carb guy and manages the temp swings. And she starts every day easy. The one thing it is fickle if I run to low on gas in the tank. She will strand ya instantly if I don’t keep fuel level up a bit. Five gallon fuel cell tho.
